What everyone said, plus the NCAA tournament.
If Olynyk had gotten the Zags to the final four, with 25/10/5 stats, people would have been whispering Larry Bird all over the place and that would have offset any combine problems because, well, you know, Bird wasn't much of an athlete either. He didn't, his last game wasn't "boffo", the combine numbers didn't impress, and all the other things came into play. This led to more of a comparison to Adam Morrison than...you know...Larry Bird.
